Permanent Solutions for Leaks, Mold & Foundation Damage
From the urban rowhomes of Wilmington, to suburban neighborhoods in Newark, and to the fast-growing communities of Middletown, New Castle County homes face serious basement challenges. Because of high rainfall, clay-heavy soil, and aging foundations, water intrusion is a common—and costly—problem.
Fortunately, at Basement Waterproofing Specialists, we provide custom-designed systems that stop leaks for good. All installations are performed by our in-house crew (never subcontractors), backed by a lifetime transferable warranty. Moreover, homeowners can take advantage of a free inspection and 15% off when booked this month.
💧 Why Basements Leak in New Castle County
- Hydrostatic pressure from clay-rich soils pushing water through foundation walls
- Foundation cracks caused by seasonal expansion and contraction
- Poor yard grading directing runoff toward your home
- Aging sump pumps or no drainage system at all
- Persistent dampness promoting mold growth
Even small leaks can worsen over time, leading to structural damage and costly repairs.
🛠 Our Complete Waterproofing Solutions:
- Interior perimeter drainage systems to channel water away
- High-performance sump pumps with optional battery backup
- Patented crack repair—permanent sealing, no fillers
- Mold-resistant vapor barriers
- Optional French drains or exterior grading improvements
Together, these solutions stop water at its source and protect your basement for life. Additionally, our systems are designed to handle both minor seepage and major storms.
